The July 2019 Challenge is now open. The target is NGC 6888 The Crescent Nebula. To reduce the number of stickies, please submit your entry to this thread.

 

The Rules will remain pretty simple:

      Your Equipment
      Your Data, Captured This Season
      Your Processing
      One Entry Per Member

 

To increase participation over such a diverse group, the winner will be selected by random drawing. Please feel free to start a thread requesting guidance on your entry prior to submitting it, the whole purpose of this challenge is to learn and compare on a common target. Entries must be submitted by midnight eastern time on July 31, and I will try to announce the winner early in August. Note: If I am late announcing, gently nudge one of the moderators in a private note, it helps. 

 

Please display an image in your post, not just a link!!

 

I hope everyone has fun with this one, and with that,

 

Let The Games Begin

 

**Disclaimer** - If the selected winner does not reply and pick a target with-in 3 days of the winner being announced the Mods will then select the next target.

~NOT A SUBMISSION~

 

Well, as usual, for historical perspective and novelty purposes only...

This is my Crescent onto film, right around thirty-three years ago!

It's a single two-hour exposure onto hydrogen-hypered film, no filtration whatsoever, hand guided.

No processing whatsoever, other than dipping it in the chemicals.

Actually, it's a pretty good rendition of how this object actually looks in my telescope.

And, without the filtration... gives a good idea of how the stars compete for attention.    Tom

These are great perspectives of the past technology and "limitations" for us. Thanks for sharing and keep them coming.

What beautiful images you people have posted!   This  one is from a SVT70mm at f/4.8 using a ASI-183MM-pro on a guided CEM-60.  HOO with 59x4min H-alpha and 39x4min OIII.  Stacked in DSS with darks, flats, and dark flats, and processed in Star Tools and Gimp.  Thanks to people recommending against bias calibrations with this camera.  Using bias, there was a lot of amp glow that was difficult to eliminate.  The large star in the upper left is named Revenant of the Swan.  Someone  had some imagination.

This is my first try ever on this target. Captured last weekend. It is not the best Crescent you can see in this forum...but I'm a beginner trying to do my best :p

Edge HD 1100 W/ 0.7x Focal Reducer on CGEM DX, ASIair, ZWO filter wheel, filters, & ASI1600mm Pro.

 

xo0hfr.jpg

 

ASI1600mm Pro @ 300 gain

100 x 60s + 150 x 120s Ha

60 x 300s Oiii

 

Images processed in pixinsight -> image calibration using only flat and darks with no calibrate/optimize setting, star alignment, integration, drizzle integration, and another star alignment to align each narrowband final image and a dynamic crop to size them to each other, and automatic background removal for each Ha/Oiii.

 

Then each was combined as HOO palette using channel combination and then SCNR to remove green and permanent stretch applied using screen transfer function and histogram transformation. The image was further processed in photoshop to increase vibrance and saturation of the color and adjust the background black level. It then was run through Topaz Denoise AI to remove noise. Finally, the image was scaled down from its native ~11000x9000 drizzle integration size down to this scale for further noise removal.

 

*Edit* I flipped my image 180 degrees, I think it accentuates the crescent shape more for some strange reason.

Hi all,

 

Here is my very first image of the Crescent Nebula. It was taken on June 22th 2019 with equipments as the followings:

Telescope: Takahashi TSA120 on AP Mach1 GTO mount, Guiding: QHY OAG, Load Star X2, Imaging camera: QHY163M

Filters: Optolong Ha=300s x 22 OIII=300s x 10 

Softwares: SGP, PHD2, Astropixelprocessor, Adobe Photoshop CC

 

Clear Skies,

 

Kijja

Amazing just freaking Amazing!!! Now days we are on autoguding, filtering and autoguding, and all remotely. Congratulations, I must say that I'll love to try something like this. Great job

Thanks; Indeed, those were the days!

 

It was like driving a car... or more like flying an airplane... and having to stay on that 2-dimensional turbulent glide-path for two or more hours, to fractional arc-sec! And once every few flights --- you crash!

 

No doubt our cars will soon have auto-pilot... first as a luxury feature... eventually standard... then only, with manual control entirely disallowed as --- too dangerous!    Tom

Well this is a sobering thread for a beginner! I tried my first DSO photo this month, successfully getting my manually aimed 200mm Newtonian pointing at this object using plate solving to confirm what I was framing. I couldn't see it on the photos but assumed stacking would reveal something. Took a series of around 30 frames of 60s each to keep the stars from trailing with my EQ5 driven mount at ISO6400. Was pleased to get round stars and learned both focusing using a Bahtinov mask and collimation of my scope optics for the first time that night.

 

After playing with the resulting images in Registax I could just about resolve the brighter arc of one edge of this nebula from the noise by pushing the levels to the limit in my image editor. So I can see where the nebula should be in my frames, but you have to imagine most of it.

 

It has been cloudy since, and now the moon is pretty bright so that's probably it for DSO for me this month.

 

Is there a real beginners thread?

Not my best by any means, but here's a capture from the night of Friday, July 12th with the super bright 80+ percent moon.  24x 180s,   20 darks, 10 flats, 50 bias, Pentax K5 astro modded, David Levy Comet Hunter,  iOptron CEM25P, guiding via MGEN II. Seeing wasn't very good.

This is an imaging competition that is open to all. Winners in the contest are picked at random, not by image quality. 

This thread is in the Beginners & Intermediate Imaging Forum. So you are in the right place to post your first images and ask questions.

great picture David!

13 hours - thats amazing. lucky if I get half that.

My SVX130T W/ WR35 arrives this week. If I am lucky maybe I can try it out with this target.

 

Ciao,
